To get table having presence of a particular text
declare @text varchar(255)
set @text = 'Vip'
select 'select * from ' + rtrim(tbl.name) + ' where ' +
rtrim(col.name) + ' like %' + rtrim(@text) + '%'
from sysobjects tbl
inner join syscolumns col on tbl.id = col.id
and col.xtype in (167, 175, 231, 239) -- (n)char and (n)varchar, there may be others to include
and col.length > 30 -- arbitrary min length into which you might store a URL
where tbl.type = 'U'To get all tables within a database along with each column in each table , its datatype and IsNUll attribute :

SELECT sh.name+'.'+o.name AS TableName ,s.name as ColumnName
